摘　　要：ITU-T L.1200规定了在电信和数据通信（ICT）设备输入端高达400 V的直流供电接口及其正常电压范围（260～400 V）。我国研究试验的240 V高压直流供电系统的正常电压范围（192～288 V）偏低偏窄，不可能成为永久性正规供电系统，或应在有限的时间内过渡到ITU建议的目标电压范围。当前研究重点显然应转向高达400 V直流电源。为此，有必要深入了解高达400 V的直流供电接口的要求、供电系统结构、接地系统设计考虑和ICT设备抗干扰试验要求等。ITU-T L.1200 specifies direct current power feeding interface up to 400V at the input to ICT equipment. It also describes the normal voltage range （260-400 VDC）. The normal voltage range （192-288 VDC） of 240V high voltage direct current power feeding system which is being developing and using in China is relatively lower and narrower. It should probably migrate to the target voltage range recommended by ITU in limited time. It describes specifications of up to 400V direct current power feeding interface, architecture of power feeding systems, design consideration of grounding system and immunity test requirement for ICT equipment.
